Osg 402-2969 Square End Mill 19/64 Inch Solid Carbide

Product Description

The OSG 402-2969 is a solid carbide square end mill designed for precision milling operations in metal and composite materials. Featuring a 19/64 inch (0.2969 inch) cutting diameter and a 13/16 inch length of cut, this two-flute tool delivers efficient chip evacuation and clean shoulder and slot milling. The micrograin carbide substrate provides hardness and wear resistance for demanding cutting conditions. At 2-1/2 inches overall length with a 5/16 inch shank diameter, this regular-length tool fits standard milling machine and machining center collets. It is suited for machinists and toolroom technicians working in job shop and production environments.

The OSG 402-2969 is used in vertical and horizontal milling operations on ferrous and non-ferrous workpieces where a sharp, uncoated carbide edge is preferred or required. The 30-degree helix angle promotes smooth cutting action and effective chip flow. The centercutting geometry allows plunge entry as well as conventional slot and peripheral milling. This tool is appropriate for general-purpose milling where an uncoated finish is specified, such as when cutting aluminum, brass, or other non-ferrous materials that may load up coated surfaces.

Key Features

• Solid micrograin carbide construction for hardness and edge retention
• Two-flute spiral design with 30-degree helix for efficient chip evacuation
• Centercutting geometry permits plunge milling as well as slot and peripheral cuts
• Right-hand cut, right-hand flute configuration for standard spindle rotation
• Uncoated finish suitable for non-ferrous and general-purpose milling applications
• Regular length profile fits standard ER and end mill holders

Compatibility

Designed as a standard replacement or production tooling option for milling applications requiring a 5/16 inch shank, 19/64 inch diameter, two-flute solid carbide square end mill in a regular-length configuration.

Installation Notes

Install in a compatible end mill holder, collet chuck, or ER collet sized for a 5/16 inch shank diameter. Ensure the spindle and workpiece are secured before engaging the cutter. Verify runout within acceptable limits for the application before beginning the cut. Follow shop safety protocols and applicable OSHA standards for rotating cutting tool use.
